Not only does attic insulation save you money on your energy bills, it will also improve the air quality inside the home. For this home we began with a deep cleaning. They removed all the dirt and debris using our heavy duty vacuums and removal hoses. Once the attic was clean the crew sanitized to get rid of bacteria and lingering odors. After this they rodent proofed this is important to prevent any future damage by rodents. Then they installed brand new R-38 insulation, this home is now comfortable and up to CA building code.
